abstract

Friction-induced vibration of a two-degrees-of-freedom mass-spring system interacting with a decelerating rigid strip is considered. The friction law is approximated by an analytic function to facilitate the numerical integration, whereas the truncated Taylor expansion of this function gives good qualitative results. It was shown that after a quasi-harmonic transient period, accompanied by viscous energy dissipation, a relatively short period of intensive stick-slip vibration occurs, with its out-of-phase component generating a series of micro-impacts on the strip. It was further shown that, because of the impulsive character of such kind of loading, its Fourier spectrum is sufficiently rich. Based on the simplified ‘normal form’ equations, it was shown that the out-of-phase vibration mode of the block system absorbs more energy from the decelerating strip if the corresponding natural frequencies satisfy the resonance condition. The out-of-phase stick-slip vibration of the blocks creates an impulsive bending moment applied to the strip, and therefore can be considered as a possible source of flexural vibration. In particular, the results are applied to explanation of squeal generation in automotive disc brakes, although the technique can be extended on other ‘squealing systems’ including geophysical fault (earthquake) models.
